Using page attribute in event handler method of controller

Hi all,
I have created a page attribute GT_TABLE. I need to use this table in one of the event handler methods of the controller of the same page. I tried to use the GET_ATTRIBUTE method but it always returns an empty table.
Can someone please guide me in this respect.
Thanking you in advance,
Regards,
Sumit.

Hi Sumit,
The page attribute you mention (GT_TABLE) it's an internal table, isn't it? So far I know, the value of internal table will gone when BSP finish to load in server. If you want to keep the data in internal table, you need to load the internal table into Session (in one of page event in BSP).

Calling the on(press) event handler

Preface
Typically when you set an event handler function for buttons by code, like:
mybutton.onPress = function(){
         trace("Hello!");
you can access and call this event handler function by:
mybutton.onPress();
and it will execute the function and trace "Hello!".
Question
But when you set event handlers on the button itself, like:
on(press){
         trace("Hello!");
is that event function accessible from code? how? I know there would be a property that you can access it by, maybe we can "decompile" an SWF to check out finally which property it stores the event code in, or would any of you have any idea?
mybutton.onPress();   // This does not work!

I don't know why, but I think it is like this. When you call the onPress() function, it will find a function called onPress, which is the onPress = function(). If you are just curious to know the answer, it is fine. If you really want to solve the problem, make a function ( for example pressed), and use mybutton.pressed(). And at the on(press) code, simply add pressed();

How to call a view without event handler onaction method.

Hi Experts,
I have develop a WD application. It has three views let view1, view2 and view3.
In view1 one button is there (onaction) which navigates to view2 through outbound plug wd_This->Fire_Out_Screen1_Plg(   ). where Out_Screen1 is outbound plug of view1.
Now view2 appears , I want that after 10 seconds view2 automatically call view3, without action on view2.
I have written like wd_This->Fire_OUT_SCREEN2_Plg( ). where OUT_SCREEN2 is outbound plug of view2, which navigates to inbound plug of view3.
But its not working. Please suggest how to and where to write code to call a view without action .

Flash Freezes up on frequent calls to XMLSocket.OnXML event handler.

Hi Everyone,
I am trying to plot data received in real time on my chumby device which supports actionscript 2. Flash however freezes due to the high data rate of my application. Does anyone know of a way to avoid freezing up the GUI due to the seemingly intensive socket communication?
Thanks in advance for your help.

Hello everyone -
Since I last posted an interesting update happened. I tested my Flex application again, it is calling a Jetty Server that returns a JSON object, in different BROWSERS. I disabled HTTPS for now, and the crossdomain.xml policy file is wide open for testing (ie. allowing every request to return data). So the app accessing the data using HTTP only. Browsers - IE, Opera, Firefox and Chrome. Each browser contained the SAME application, revision of the Flash Player (10.3.183.10 debugger for firefox, chrome, opera, safari PC; 11.0.1.129 consumer version in IE9,) take a look at the screen shot (safari not shown although the result was the same as IE and chrome)
Note that Opera and Firefox returned successful values (i.e. successful JSON objects) using the same code generated from the Data Services Wizard. Chrome, IE and, Safari failed with an Internal error. So I am left wondering - WHY? Is it something with the Flash Player? the Browsers? the Flex SDK? Any thoughts are appreciated. Again, the code is found in the original thread above.

Input value given on web page is not getting pickedup in event handler

Hi friends,
I have created one simple page in SE80 with program with flow logic option, in which I would like to show business partner details from BUT000 table with the input of partner number. But the thing is the input value(partner no.)which I am giving on web page is not getting picked up in selection in event handler though I am giving input value it is becoming initial while selecting. What could be the reason?
Below I am mentioning the code which I have written in even handler for OnInputProcessing event.
CASE EVENT_ID.
WHEN 'select'.
NAVIGATION->SET_PARAMETER( 'partner' ).
SELECT * FROM but000 INTO TABLE I_but000 WHERE partner BETWEEN partner AND partner1.
WHEN OTHERS.
ENDCASE.
Thanks in advance,
Steve

Event handler of inbound plug not called when plug fired by event handler

Hello All,
I have a rather bizzare problem, hopefully someone out there can figure out what is going on, as I'm rather stumped.
I have 2 views, A and B. They are linked by plugs, InA, InB, OutToA, OutToB. OutToB is linked to InB from A to B, OutToA is linked to InA from B to A.
There is an onActionLink in view A. Clicking on this triggers an action which calls the wdFirePlugOutToB method.
In view B some handling is done in the method onPlugInB, then wdFirePlugOutToA is called to change the displayed view back to A.
As far as the user is concerned they don't ever see view B. (this bit works perfectly!)
Now also in view A I have an event handler which handles a event from the component controller. It also calls wdFirePlugOutToB.
If I trigger an event in the component controller this event handler is called and the method called. However, when I put a breakpoint in the onPlugInB, flow never reaches here. Flow does get to the wdDoModifyView of view B but never to the inbound plug event handler.
Any suggestions as to what I might need to do? I would have thought calling the wdFirePlugOutToB method would ALWAYS trigger the linked event handler onPlugInB.
I am running NW04 SP18.
Thanks!

Hi Bharathwaj,
The project I'm working on has a requirement to allow for a road-mapped process (FPM) which has one step in which multiple screens can be accessed. I'll give an example: A user in step A selects the cost centre that they want to work with, in step B they need to maintain several pages of information about this cost centre. The do not want to break this information into steps, as there is no logical progression from one step to the next, and it may well be that the user wishes to go from maintaining screen 1 to screen 3, and then screen 2, and then screen 4. Stepping between all screens (1->2->3->2->3->4) wastes time and is not very user friendly. Step C of the process confirms the data that the user entered in step B, and Step D is the validation that the changes have been committed to the database. (a very familar 4 step process for those using ESS).
To allow for this requirement, I have designed a left navigation pane type screen. links appear on the left of the screen and the user can use these to navigate between different screens (implemented as FPM IVAC VCs) on the right of the screen.
It is quite an elegant solution (even if I do say so myself although quite complex to implement. I have relied very heavily on reading the code SAP put together for the FPM. The most complex part is that in order to update the the content of view containers in an application you must trigger a web dynpro view navigation by firing a plug to a different view.
Unfortunately I don't have any sample application code, only the finished product, which I can't really share. But I can say that if you look at the FPM code carefully, working from where the wdInit of the FPM is called, it will eventually make sense.
One thing I found slightly frustrating, you can't use the FPM's component usage register (FPM method attachComponentUsage(IWDComponent, IWDComponentUsage)) to add a VC... darned inconvienient really (you'd think that the web dynpro framework could have implemented the concept of extending an interface, but the IBLC and IVAC interfaces are different! - even though the IVAC is just IBLC + a few methods), but then again you can manage the instantiation of the used VC yourself and call the onInit method of the VC passing the current fpm reference, to attach it to a common FC, and given that you should be sharing context through the FC and never the VC, then really this isn't too much of an issue. (I spent ages worrying that I couldn't add the instances of the VC that I was using within my navigation pane VC to the fpm instance list, until I realised that it really didn't matter!)
One day - when I have time (yeah right!) I might put together a blog about this sort of stuff, in the meantime, it keeps me plenty busy enough not to have the time!
Hope this helped in some small way,
Cheers,
Chris

How to Call Event Handler Method in Another view

Hi Experts,
                   Can anybody tell me how to call Event handler Method which is declared in View A ,it Should be Called in
view B,Thanks in Advance.
Thanks & Regards
Santhosh

hi,
1)    You can make the method EH_ONSELECT as public and static and call this method in viewGS_CM/ADDDOC using syntax
    impl class name of view GS_CM/DOCTREE=>EH_ONSELECT "method name.
             or
2)The view GS_CM/ADDDOC which contains EH_ONSELECT method has been already enhanced, so I can't execute such kind of operation one more time.
                     or
3)If both views or viewarea containing that view are under same window , then you can get the instance ofGS_CM/DOCTREE from view GS_CM/ADDDOC through the main window controller.
lr_window = me->view_manager->get_window_controller( ).
    lv_viewname = 'GS_CM/DOCTREE '.
lr_viewctrl ?= lr_window ->get_subcontroller_by_viewname( lv_viewname ).
Now you can access the method of view GS_CM/DOCTREE .
Let me know in case you face any issues.

How to call a static method from an event handler

Hi,
I'm trying to call a static method of class I designed. But I don't know how to do it. This method will be called from an event handler of a web dynpro for Abap application.
Can somebody help me?
Thx in advance.
Hamza.

To clearly specify the problem.
I have a big part code that I use many times in my applications. So I decided to put it in a static method to reuse the code. but my method calls functions module of HR module. but just after the declaration ( at the first line of the call function) it thows an exception. So I can't call my method.

Server side function not get called after dispatching cairngorm event second time on same page

Hi All,
I am facing a urgent issue regarding cairngorm event. Actually my page contain 3 button add,delete,save
and clicking of any button I do the respected functionality. For ex:
I click the add button & on clicking of add button I fire a cairngorm evnt & after getting response from server side that the record is added
I displayed a message that the record is added & update the data source.
After addition of the record , with out going to other page if I perform the same functionaly(Like adding another record) on same page the cairngorm
event not call the server side function - after debugging I find out that cairngorm event reach to the corresponding excutecommand function & called that function but it is not calling my server side function & I also din't get any error message .
I dont know why the server side function not get called?. similarly if I try for delete or update case the same things happend. Only for the first time it works properly but not for the second time.
Could any of you please tell me why the cairngorm event not calling the server side function.
Thank you for your kind assistance.
Regards,
Ujjwal

Okay, well I think I've worked out the problem.
In ASP.NET we would typically bind repeating controls such as DataLists and Repeaters manually using <i>Control</i>.DataBind(), because we're usually using a separate class library containing collections for our objects. Seems the SAP Table control doesn't like this approach.
I changed the code so that the databinding is specified on the control, and call the Page's DataBind() method and it all worked fine.
One tip: because the collection I used to bind to is in a separate class library, I receieved a <i>BC306523: Reference required to assembly MyAssemblyName...</i> message, even though I had a reference to the assembly in my project and the DLL is being properly deployed. To fix this, you must include the following directive at the top of the component's ASCX file:
<%@ Assembly Name="AssemblyName" %>

Event handler when using partial page refresh ?

Hi
I have a calendar, which uses partial page refresh. The problem is how to make javascript wait until the calendar has loaded and then do some updates on the calendar (after the user has pressed the next button that runs apex.widget.calendar.ajax_calendar('S','next');, for example ). I thought I could add "onreadystatechange" (or onload) event handler to the calendar like this: onreadystatechange="checkState()", where the function would check the state and if ready then do the updates. This doesn't work. Could somebody please tell me why not ?
Tiina

Hi,
It seems that ajax calendar missing event apexafterrefresh.
I do not know is this "bug" or just feature.
That event would be useful to your case , if I understand correct what you looking for.
For workaround , you can over write original function by placing this to calendar region footer
<script>
apex.widget.calendar.ajax_calendar=function(p_calendar_type, p_calendar_action, p_calendar_date, p_calendar_end_date){
var l_cal_type_field = $v('p_cal_type_field_id');
var l_cal_date_field = $v('p_cal_date_field_id');
var l_cal_end_date_field = $v('p_cal_end_date_field_id');
var l_cal_id = $v('p_calendar_id');
var l_calendar_region = 'calendar' + l_cal_id;
if ( p_calendar_type != 'C' ){
$s(l_cal_date_field,$v('p_calendar_date'));
}else{
if ( $v(l_cal_date_field) == '' ) {
   $s(l_cal_date_field,$v('p_calendar_date'));
if ( $v(l_cal_end_date_field) == '' ) {
   $s(l_cal_end_date_field,$v('p_calendar_end_date'));
// create and apex.ajax.widget object
var a = new apex.ajax.widget('calendar',function(){
/* start the return function */
if(p.readyState == 1){
   document.body.style.cursor = "wait";
}else if(p.readyState == 2){
}else if(p.readyState == 3){
}else if(p.readyState == 4){
   $x(l_calendar_region).innerHTML = p.responseText ;
   $s(l_cal_date_field,$v('p_calendar_date'));
   if (p_calendar_type == 'C') $s(l_cal_end_date_field,$v('p_calendar_end_date'));
   document.body.style.cursor = "";
/* DO HERE THINGS AFTER CALENDAR REFRESH */
}else{return false;}
// code for next,previous and today
if (p_calendar_type == 'S'){
p_calendar_type = $v('p_calendar_type');
}else{
$s(l_cal_type_field,p_calendar_type);
a.ajax.addParam('p_widget_mod',p_calendar_type);
a.ajax.addParam('p_widget_action',p_calendar_action);
a.ajax.addParam('x01',l_cal_id);
var lDate = (!!p_calendar_date && p_calendar_date !== '')?p_calendar_date:$v(l_cal_date_field);
if (p_calendar_type == 'C') {
var lendDate = (!!p_calendar_end_date && p_calendar_end_date !== '')?p_calendar_end_date:$v(l_cal_end_date_field);
a.ajax.add(l_cal_date_field,lDate);
if (p_calendar_type == 'C') a.ajax.add(l_cal_end_date_field,lendDate);
a.ajax.addParam('x02',lDate);
if (p_calendar_type == 'C') a.ajax.addParam('x05',lendDate);
a.ajax.add(l_cal_type_field,p_calendar_type);
a._get();
</script>Where I have comment *"do here things after calendar refresh"*, you can hook own scripts.
Of course this is not best way, but might help you till ajax calendar support dynamic actions fully

Call to pl/sql from java event-handler

How can I call pl/sql procedure or function from java-script event handler
Thanks,
Anna

Anna,
You cannot call any arbitrary PLSQL code from the forms, only "standard"/custom event handlers can be called through do_event Javascript fuction, syntax :
do_event(this.form,this.name,1,'ON_CLICK,'');
where:
1 - button intstance, if you have more than one instance of the same button on the screen this should be 2,3,4.....
'ON_CLICK' - is the predefined event type
'' - the last argument is any user defined string which will passed down to the PLSQL event handler.
Thanks,

How to call the event handler of other application....?

Hi,
I am working on two applications.
Now i need to call a Event handler from my first application to my second application.
I need a same process in this aaplication also. So i need to call the event handler of that application.
So, Kindly tell me about the process to call the even handler of another application.
Thanks in Advance.
Regards,
Prithivi

hi,Prithivi..
Unfortunately, as far as i know, i should tell you that : you cann't call the event-hanlder in another Application if the 2 applicaions are run in different IE browser...
If your 2 component are used in the same IE browser, maybe you can make one interface event, and trigger it in one component, then handle the event in the second component(by reimplemented the former)...
However, from your description, i think, you want to trigger the event handler in another application in different IE Browser...
So, very upset..We cann't communicate between the 2 applications, as far as i know...
Best wishes.

Java Event Handling in JSP Pages

Dear All:
This is what I wanna do. when user enters text in my <input type="text" ... > in my JSP page, I want to take this user entered data and convert it in another language simultaneously as the user is inputting text in another textarea.
Right now the only choice I have is onChange="convert()" Javascript function.
But I dont want to use Javascript as I already have a Java class which does that for the Swing GUI client.
Is their a way i can embed java for event handling in jsp.
thanks,
Chetan

only if you use an applet, javascript, etc.
remember, jsp is server-side, not client-side
what the client sees is html or whatever (i.e. static content)

Call event handler programatically

Hi, I have a function that handles a change event from a
combo box. The problem is that, I also want to call the function
from within the program, but the function is waiting for a change
event. Is it possible to call an event handler
programatically?

if you're not using the event that is passed to the event
handler, then you can initialise the event to null, which means
that Flash won't worry if no event is passed to the event handler,
and you could either call this as a function or use it as an event
handler eg:
function comboChange(event:Event=null):void
if you were using the event handler(which is probably the
best idea to target the combo from event.currentTarget rather than
directly in case you want to extend this handler in future), then
it might be nicer to do this sort of thing:
